Napa County is located north of the San Francisco Bay Area in California. At the north end of Napa County is the Bay Area's second tallest peak Mount Saint Helena, and to the far south of Napa County lays the section of the Napa Valley that bleeds into Carneros. When the first white settlers arrived in the early 1830s, there were six tribes in the valley speaking different dialects and they were often at war with each other. The Mayacomos tribe lived in the area where Calistoga was founded. Napa County was one of the original counties of California, created in 1850 at the time of statehood. Napa Valley is widely considered one of the top wine regions in California and all of the United States. By the end of the nineteenth century there were more than one hundred and forty wineries in the area. Today Napa Valley features more than two hundred wineries and grows many different grape varieties including Cabernet Sauvignon, Chardonnay, Merlot, and Zinfandel. The region is visited by as many as five million people each year, making it the second to Disneyland as the most popular tourist destination in California.
